Jose D. Fuentes from Penn State stopped by to visit with the Biomet Lab and discuss science

Sebastian Wolf, ETH Zurich, and Biomet alumnus, dropped by on his way to Sagehen and research in the Sierras. It was great to catch up.


Robert Shortt and Camilo Rey Sanchez hosted and guided Andrew Oliphants atmospheric science class from San Francisco State Univerisity on a tour of our delta field sites. We've been hosting Andrew and his class for many years now and Robert is a product of one of those early field trips.
